STEREOSCOPE.

SPECIFICATION forming part of Letters Patent No. 502,450, dated August1, 1893.

Application filed January 12, 1893. Serial No. 458,099. (No model.)

To all whom it may concern:

Be it known that I, ANTON WAGNER, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Stereoscopes, whichimprovement is fully set forth in the following speci- Iication andaccompanying drawings.

My invention consists of a stereoscope having a plate with lensestherein, and a picture holder formed of extensible parts, as hereinafterdescribed, and adapted to be folded against said plate.

It also consists of a catch on said plate for engaging the side portionsof said picture holder, as hereinafter described and claimed.

Figure l represents a perspective view of a Stereoscope in foldedcondition embodying my invention. Fig. 2 represents a view of the samein operative condition.

Similar letters of reference indicate corresponding parts in the twofigures.

Referring to the drawings:-A designates a plate formed of any suitablematerial and having lenses B secured thereto.

C designates a holder formed of the extensible parts D and E connectedby suitable eyes, the part E having a limb F which is mounted by meansof eyes G, upon the plate A, said limb acting as a shoulder which abutsagainst the plate when the holder is in operative position, and sustainsthe same as shown in Fig. 2. On the outer end of the part D is a clamp Hfor supporting a picture or other object thereon, as shown in dottedlines Fig. 2. In the present case, the holder C is formed of wire, andthe clamp H formed by bending the wire into coils of such shape that apicture, duc., may be inserted between the bends and readily held by thesame.

Mounted on the plate A, below the axis of the holder, is a lock or catchJ for said holder, the same consisting of a bar or rod which is mountedin eyes K secured to the plate A, one end of said rod being bent forminga crank L, and the other end having a hook M thereon.

The operation is as follows, when the parts A and the holder retained inextended and operative position, as shown in Fig. 2. Vhen the lock isproperly drawn back, it is disengaged from the limb F, and may then beturned and folded against the plate A. The part D of the holder is thenpushed in, so as to fold upon the part E, and the holder is then foldedagainst the plate A, all as will be seen in Fig. l. In this position ofparts the stereoscope may be readily carried in the pocket or storedaway, packed, transported. tbc.

Having thus described my invention, what. I claim as new, and desire tosecure by Letters Patent, is

l. A stereoscope consisting of a plate having lenses therein, a pictureholder formed of extensible parts connected by suitable eyes, one ofsaid parts having a limb mounted in eyes on the said plate, and theother part having at its outer end a picture clamp, and a locking barfor said holder secured to said frame, said parts being combinedsubstantially as described.

2. A stereoscope having a plate with lenses, a picture holder secured toand adapted to be folded against said plate, and a catch journaled ineyes on said plate and having ends adapted to contact with the sideportions of said holder, said parts being combined substantially asdescribed.

3. In a stereoscope, a lock for the picture holder thereof consisting ofa rod journaled in eyes on the plate of said stereoscope, and having ahook on one end and a crank on the other, substantially as described.
